请注意：此 API 现在已过时。
返回InitEventArgs对象中传递的接口的名称。
命名空间： Microsoft.SharePoint.WebPartPages
程序集： Microsoft.SharePoint（位于 Microsoft.SharePoint.dll 中）
语法
声明
<ObsoleteAttribute("Use ConnectionProvider or ConnectionConsumer attribute to create ConnectionPoint instead.")> _
Public Overridable Function GetInitEventArgs ( _
InterfaceName As String _
) As InitEventArgs
用法
Dim instance As WebPart
Dim InterfaceName As String
Dim returnValue As InitEventArgs
returnValue = instance.GetInitEventArgs(InterfaceName)
[ObsoleteAttribute("Use ConnectionProvider or ConnectionConsumer attribute to create ConnectionPoint instead.")]
public virtual InitEventArgs GetInitEventArgs(
string InterfaceName
)
参数
InterfaceName
类型：System.String使用转换器的Microsoft.SharePoint.WebPartPages.Communication命名空间中的接口。
返回值
类型：Microsoft.SharePoint.WebPartPages.Communication.InitEventArgs
InitEventArgs 对象，如 Web 部件可实现ICellProvider接口返回CellProviderInitEventArgs对象。
备注
GetInitEventArgs方法才所需的Microsoft.SharePoint.WebPartPages.Communication命名空间，可以使用转换器，如IRowProvider、 ICellConsumer、 IFilterConsumer、 IParametersOutProvider和IParametersInConsumer接口的接口。创作用于创建一个连接，需要转换器所需的所有初始数据的用户界面的基于 Web 的连接调用InitEventArgs方法。它是必须由开发人员使用转换器的接口重写WebPart虚拟方法。如果没有重写，则显示一条错误消息。
示例
下面的代码示例演示重写的GetInitEventArgs方法。此代码示例是示例的一个更大提供的ICellConsumer接口的一部分。
创建可连接的 Web 部件的各个步骤的概述，请参阅Creating a Connectable Web Part。
' Step #11: Override the GetInitEventArgs() method.
' The GetInitEventArgs method is called by the Web Part infrastructure during the
' ASP.NET PreRender event to gather the necessary information it needs to build
' the transformer dialog box. The transformer dialog box
' is needed when connecting different interfaces such as IRowProvider
' to ICellConsumer. The transformer dialog box allows the user to map the fields between the
' interfaces. The GetInitEventArgs method only needs to be implemented for interfaces that
' can participate in a transformer which are the following:
' ICellConsumer, IRowProvider, IFilterConsumer, IParametersOutProvider, IParametersInConsumer.
' interfacename is the name of interface on which the Web Part infrastructure is requesting
' information.
' Returns an InitEventArgs object.
Public Overrides Function GetInitEventArgs(interfaceName As String) As InitEventArgs
' Check if this is my particular cell interface.
